Miniature Rose Plant Named &#39;KORpot084&#39;

ABSTRACT

A new and distinct variety of Miniature Rose Plant, herein referred to by its cultivar name, ‘KORpot084’, is provided which forms in abundance on a substantially continuous basis attractive, red and pink striped colored blossoms. The vegetation is vigorous and the growth habit is compact. Attractive ornamental foliage is formed with good disease resistance. The new variety is particularly well suited for providing distinctive ornamentation in the landscape.

Botanical/commercial classification: Latin name—Rosa hybrida. Commonname—Miniature Rose Plant.

Varietal denomination: ‘KORpot084’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Miniature Rose Plant of the presentinvention was created during 2014 at Offenseth-Sparrieshoop, Germany byartificial pollination wherein two parents were crossed which previouslyhad been studied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., seed parent) of the newvariety was an unnamed seedling (non-patented in the United States). Themale parent (i.e., pollen parent) of the new variety was the ‘KORpot28’variety (U.S. Plant Pat. No. 25,004).

The parentage can be summarized as follows:

unnamed seedling x ‘KORpot28’

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new Miniature Rose Plant of the present inventionpossesses the following combination of characteristics:

(a) abundantly and substantially continuously forms attractive, red andpink striped colored blossoms,

(b) exhibits a compact growth habit,

(c) forms vigorous vegetation, and

(d) forms attractive ornamental foliage with good disease resistance.

The new variety well meets the needs of the horticultural industry. Itcan be grown to advantage as ornamentation in parks, gardens, publicareas, and in residential settings. Accordingly, the plant isparticularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. Morespecifically, the unnamed seedling female parent (i.e., seed parent)exhibits a lower petal count and a taller growth habit compared to newvariety and displays red and yellow striped flowers, whereas the newvariety displays red and pink striped flowers. Additionally, the‘KORpot28’ variety (i.e., pollen parent) exhibits a solid dark redcolored flower and taller growth habit compared to the red and pinkstriped colored flower and shorter habit of the new variety. Moreover,new variety can be readily distinguished from other similar non-parentalvarieties. For example, the ‘KORpot056’ variety displays orange andyellow striped flowers, whereas the new variety displays red and pinkstriped flowers and has a more compact and less upright growth habit anda shorter shelf life than the ‘KORpot056’ variety.

The new variety has been found to undergo asexual propagation in KleinOffenseth-Sparrieshoop, Germany by a number of routes such as vegetativecuttings. Asexual propagation techniques in Germany have shown that thecharacteristics of the new variety are homogeneous, stable, and strictlytransmissible by such asexual propagation from one generation toanother. Accordingly, the new variety undergoes asexual propagation in atrue-to-type manner.

The new variety has been named ‘KORpot084’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonablypossible to make the same in color illustrations of this character, atypical specimen of the new variety. The illustrated rose plant of thenew variety was approximately twelve weeks of age and was observed atKlein Offenseth-Sparrieshoop, Germany while growing indoors on its ownroots in a 10.5 cm container.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart, 2015 edition). Theterminology which precedes reference to the chart has been added toindicate the corresponding color in more common terms. The descriptionis based on the observation of a one-year-old specimen of the newvariety, observed during July, while growing in a one-gallon containeron its own roots in a greenhouse in Cochranville, Pa.

Plants of the ‘KORpot084’ variety have not been observed under allpossible environmental conditions to date. Accordingly, it is possiblethat the phenotypic expression may vary somewhat with changes in lightintensity and duration, cultural practices, and other environmentalconditions.
